Are electrostatic forces always attractive?

The electrostatic force is a very large force. There are two types of charges: positive charges and negative charges. Like charges repel each other and unlike charges attract each other. Therefore, electrostatic forces are not always attractive.

Is electrostatic force always repulsive explain your answer?

Electrostatic force is that force that acts between two charged bodies. … So, the electrostatic force between two positive and negative charges will always be attractive but the electrostatic force between two positive charges and that between two negative charges will always be repulsive.

What is the electrostatic force of attraction?

The electrostatic force is an attractive and repulsive force between particles are caused due to their electric charges. The electric force between stationary charged bodies is conventionally known as the electrostatic force. It is also referred to as Columb’s force.

Is electric force both attractive and repulsive?

The electric force F E F_E FE​F, start subscript, E, end subscript can be either attractive or repulsive. Opposite charges, such as a positive charge and a negative charge, attract each other. Like charges, such as two negative charges or two positive charges, will repel each other.

What are attractive and repulsive forces?

Repulsion is a movement between two charges that are identical or similar. The power that exists between two electrons (negative charge). Attraction is a force between two charges that are distinct or unlike. … Repulsive forces occur only when atoms are very close to each other.

What makes a force attractive or repulsive?

The Coulomb force between two or more charged bodies is the force between them due to Coulomb’s law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.

How strong is electrostatic force?

Majority of the induced electrostatic force is weak in nature, however, some electrostatic forces such as the one between an electron and a proton that make up a hydrogen atom is 36 orders of magnitude stronger than the gravitational force acting between them.

Is electrostatic force conservative force?

The electrostatic or Coulomb force is conservative, which means that the work done on q is independent of the path taken, as we will demonstrate later. This is exactly analogous to the gravitational force.

Is electrostatic force contact or noncontact?

Electrostatic forces are non-contact forces; they pull or push on objects without touching them.

What determines whether the electrostatic force between two charged particles is attractive or repulsive?

Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges. The size of the force varies inversely as the square of the distance between the two charges.

Can an electrostatic force be repulsive?

The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force. … If the charges have the same sign, the electrostatic force between them is repulsive; if they have different signs, the force between them is attractive.

Is strong nuclear force attractive or repulsive?

The nuclear force is powerfully attractive between nucleons at distances of about 1 femtometre (fm, or 1.0 × 1015 metres), but it rapidly decreases to insignificance at distances beyond about 2.5 fm. At distances less than 0.7 fm, the nuclear force becomes repulsive.

Why are attractive forces negative?

That’s all right,but I want to know whenever we use a work done by an attraction force we use a negative sign,viz: the gravitational potential.It is written in books that the gravitational potential is negative because the work to bring an object from infinity to the gravitational field is done by the gravitational …
